With the popularization of multi-core processors, transaction memory, as a concurrent control mechanism with easy programing and high scalability, has attracted more and more attention. As a result, the reliability problems of transactional memory become a concerning issue. This paper addresses a transactional implementation of the Lu benchmark of SPLASH-2, and proposes a fault-tolerant Lu algorithm...
In this paper, examples are used to explain that the density-based clustering algorithm fits for grouping students according their score. And GDLD algorithm is used to analyze the information of students from School of Distance Education of Tianjin University so as to provide some useful inspiration on further study of learning mode. So teaching managers could make a much better understanding of students'...
Conventional restaurant service is passive: meal-ordering is excessively relying on the interaction with waiters to channel the order into the kitchen. However, privacy on meal ordering and entertainment access, as well as order fulfillment, is desirable in a top-notch customer-centered service system. To realize this, the multi-touchable e-restaurant system is proposed. The system uses technologies...
In this paper, we introduce a system that synthesizes the emotional audio-visual speech for a 3-D talking agent by adopting the PAD (Pleasure-Arousal-Dominance) emotional model. A GMM-based method is introduced to predict variation of acoustic features for emotional speech by PAD values, and a parametric framework of PAD-driven emotional facial expression synthesis is built. As the focus of this paper,...
Application-level checkpointing can decrease the overhead of fault tolerance by minimizing the amount of checkpoint data. However this technique requires the programmer to manually choose the critical data that should be saved. In this paper, we firstly propose a live-variable analysis method for MPI programs. Then, we provide an optimization method of data saving for application-level checkpointing...
